SpringBoot+MINIO

1. Linux安装MINIO

   https://blog.csdn.net/tongxin_tongmeng/article/details/133934115

2. MINIO创建桶
   
   
   
3. MINIO创建秘钥
   
   
   
   
4. MINIO的API路径

   http://your-server-ip:9000
   注意：API路径在日志文件中/opt/minio/minio.log

   
5. pom.xml

   
   
   	com.amazonaws
   	aws-java-sdk-s3
   	1.12.566
   

6. application.yml

   aws:
     s3:
       accessKey: minio_access_key
       secretKey: minio_secret_key
       url: http://your-server-ip:9000
       bucket: minio-bucket
   
   spring:
     servlet:
       multipart:
         max-file-size: 100MB
         max-request-size: 100MB

7. 配置类

   @Data
   @Configuration
   @ConfigurationProperties(prefix = "aws.s3")
   public class AwzS3Config {
       private String accessKey;
       private String secretKey;
       private String url;
       private String bucket;
   }

8. 工具类

   @Component
   public class AwzS3Util {
   
       @Resource
       private AwzS3Config injectAwzS3Config;
   
       private static AwzS3Config awzS3Config;
